Background: Neural tube defects (NTDs) are severe congenital malformations that arise from failure of neurulation during early embryonic development. The molecular basis underlying most human NTDs still remains largely unknown. Based on the hypothesis that folic acid prevents NTDs by stimulating methylation reactions, DNA methylation changes could play a role in NTDs.

Neural tube defects (NTDs) are common birth defects of complex etiology. Though family- and population-based studies have confirmed a genetic component, the responsible genes for NTDs are still largely unknown. Based on the hypothesis that folic acid prevents NTDs by stimulating methylation reactions, epigenetic factors, such as DNA methylation, are predicted to be involved in NTDs.

Aims: Intravesical instillation of oxybutynin is an accepted and effective treatment in children with neuropathic bladder-sphincter dysfunction, when oral oxybutynin results in inadequate suppression of detrusor overactivity or intolerable side effects. However, as yet no data are available on long-term use and outcome.

Methods: A patient cohort with detrusor-sphincter dyssynergia that started oral oxybutynin between 1995 and 1997 was re-evaluated 15 ± 1 years after the switch from oral to intravesical (n = 10), with urodynamic investigations, renal ultrasounds, DMSA-scintigraphy, (51)Cr-EDTA-clearance, and validated questionnaires on incontinence and quality of life.

Background: Significant bacteriuria (SBU) and urinary tract infections (UTIs) are common in patients with spina bifida and neuropathic detrusor sphincter dysfunction. Laboratory agar plated culture is the gold standard to establish SBU. It has the disadvantage of diagnostic and subsequent therapeutic delay.

Purpose: Antibiotic prophylaxis (low dose chemoprophylaxis) has been prescribed since the introduction of clean intermittent catheterization in children with spina bifida. We hypothesized that stopping low dose chemoprophylaxis does not increase the number of urinary tract infections in these patients.

Materials And Methods: A total of 176 patients with spina bifida participated in a randomized controlled trial (ISRCTN trial number 56278131) of either continuation or discontinuation of low dose chemoprophylaxis.

The aim of this randomized, placebo-controlled study was to explore the effect of metformin in children with a neurogenic or myogenic motor deficit, who are therefore prone to develop overweight, adiposity, and insulin resistance. Study participants (n = 42) had a mean age of 15.5 yr, a short stature (height -2.

Neurogenic bladder sphincter dysfunction (NBSD) can cause severe and irreversible renal damage and bladder-wall destruction years before incontinence becomes an issue. Therefore, the first step in adequate management is to recognize early the bladder at risk for upper- and lower-tract deterioration and to start adequate medical treatment proactively. Clean intermittent catheterization combined with anticholinergics (oral or intravesical) is the standard therapy for NBSD.

Background: In very rare dysraphic cases, it is not clear whether the primary abnormalities are in the neural elements, or in the bony elements.

Case Description: We describe a case of segmental hypoplasia of the spinal cord, with absent nerve roots in the afflicted segments, and associated meningocele and vertebral abnormalities. We illustrate the arguments for and against the classification of this lesion either as an atypical case of myelomeningocele (MMC) or as a mild case of segmental spinal dysgenesis (SSD).
